He added: "This is it, it does not get any bigger than this. You've got the two unbeaten heavyweights, both over 6ft 6in, both 18 stone-odd, both unbeaten. One lineal champion of the world, one unified champion of the world.

"Has this ever happened before with both unbeaten? OMG I am so excited, I hope you guys are.

"Biggest fight ever in British boxing history. So proud to be involved in it. The fans are the only winners."

Joshua's promoter Eddie Hearn, meanwhile, has admitted he would love to see his fighter take on the controversial former Fury next year.

Joshua successfully defended his IBF and WBA heavyweight titles against Carlos Takam in Cardiff on Saturday and either WBO champion Joseph Parker and WBC champion Deontay Wilder appear the most likely next opponents.

However, Hearn has not ruled out the prospect of a headline-grabbing bout with Fury, who is still waiting for a final ruling from UK Anti-Doping on a suspended drugs ban after the hearing was adjourned in July.

"I think the Wilder fight is potentially one of the biggest in world boxing and I think that fight is realistically going to happen in the summer of 2018," he told BBC 5 Live.

"But Tyson Fury is a guy who we'd love to see come into the sport. Whether that'll happen or not is another issue.

"The problem for him is to overcome the governing body and UK Anti-Doping.

"I think he will come back. I think at some point he will wake up one morning and think, 'I've got to get myself together here' and go challenge in these big fights.

"If he does, with one or two fights, then I'd love to see the Anthony Joshua fight and I'd like to see it in 2018."
